Autologous Chin Augmentation with Cervico-mental Angle Correction in Burn Scar Contracture

Microgenia, retrogenia, cervico-mental angle obtusity, and lower lip ectropion are complications of severe burn scar contracture and are associated with functional and psychosocial disturbances. These complications can be managed in several ways, for example using fat or dermo-fat flap as autologous tissue transposition appears appropriate for simultaneous chin augmentation with cervico-mental angle improvement. We aimed to delay skin grafting to increase the chance of complete integration. From November 2015 to February 2023, 12 patients who underwent surgical treatment with fat or dermo-fat flap and delayed skin graft were included in the study. In this prospective study, we measured the cervico-mental and Legan's angles using the Digimizer Software pre- and post-operatively on 8 (7 female, 1 male) eligible patients who signed the informed consent. Although several methods are available for chin augmentation, transposition of tissues through structural rearrangement to address all the problems appears to be a cost-effective alternative for patients with obtusity due to hypertrophic scar of cervico-mental area with microgenia and retrogenia.
